Problems solved by technology

In the era of more and more pursuit of high performance, environmental protection, energy saving, and personalization, the interior of a car, like the shape of a car, has become an important factor for people to buy a car, so the requirements for car interiors are also increasing. The higher the value, the traditional old-fashioned back-spun cotton compression molding will not only have poor formability, but will also cause product surface material marks and fool-proof marks to be unclear, which will affect product quality and affect smooth delivery to OEMs
Now more and more materials are being developed and applied in the automotive field, the cost is getting lower and lower, and the performance is getting better and better, but better environmental protection processing technology needs to be developed

Abstract

The invention relates to a production process of an automobile sound-insulating and heat-insulating pad. The production process comprises the following steps of: putting thermoplastic reconstituted cotton of soft and hard layers into a ceramic far-infrared heating oven for suspension type heating, controlling the temperature of upper and lower heating areas to be 280-320 DEG C, and controlling the heating time to be 170-180s; adopting a punching mold internally provided with a cooling water circulating system, continuously introducing cooling water with the temperature being 6-8 DEG C; installing an upper mold and a lower mold of the punching mold on a forming machine; putting the heated thermoplastic reconstituted cotton of soft and hard layers between the upper mold and the lower mold of the punching mold; starting the forming machine to lead the upper mold and the lower mold of the punching mold to be pressed tightly; controlling the forming and pressing pressure to be 8-10MPa, controlling the pressure maintaining time to be 60-80s and obtaining a crude product of the automobile sound-insulating and heat-insulating pad; and trimming the obtained crude product of the automobile sound-insulating and heat-insulating pad and obtaining the automobile sound-insulating and heat-insulating pad. In the production process, the operation is simple and practical, no harmful substances are generated in the whole production process, so that the production process belongs to an environmentally-friendly type process.

Description

technical field [0001] The invention relates to the technical field of automobile interior parts, in particular to a production process of an automobile sound-insulating and heat-insulating pad. Background technique [0002] Automotive interior parts are generally installed on the top of the car, the trunk, and the cab, and the tire sheet metal plays the role of heat insulation, sound insulation, aesthetics and practicality. In the era of more and more pursuit of high performance, environmental protection, energy saving, and personalization, the interior of a car, like the shape of a car, has become an important factor for people to buy a car, so the requirements for car interiors are also increasing. The higher the value, the traditional old-fashioned back-spun cotton compression molding will not only have poor formability, but will also cause product surface material marks and fool-proof marks to be unclear, which will affect product quality and affect smooth delivery to O...
